8. Life Cycle
8.1
What is the expected life cycle of your product under normal use.
8.2
Have you performed any test to establish this life cycle.
8.3
Do you have any data to establish this life cycle without test.
9. Degradation of properties over time:
9.1
Strengths:
Have you established any change with time in compressive strength, tensile strength and
shear strength of the material constituting your vinyl sheet pile products by exposure to out
door conditions (sunlight). If so, what is the rate of change?
9.2
Elastic modulus:
The value of elastic modulus controls the stiffness or deflection of the installed sheet piles.
Have you established any change with time of the elastic modulus of the material constituting
your vinyl sheet pile products by exposure to out door conditions (sunlight). If so, what is the
rate of change?
9.3
Creep:
Thermoplastic polymers are known to creep under a sustained stress. Have you established
the creep rate for the final polymer mix that constitutes the material of your vinyl sheet pile
products? If so, what it is.
9.4
Impact Resistance:
Have you established any change with time the impact resistance of the material constituting
your vinyl sheet pile products by exposure to out door conditions (sunlight). If so, what is the
rate of change?
10. Any other information you consider pertinent to these studies.
